[Computed tomography in the diagnosis of and tactics of treating abscesses of the brain].

The authors analyse 20 patients with brain abscesses of rhinosinusogenic etiology who were subjected to computed tomography (CT). CT allows exact localization of the abscess, appraisal of its size and depth, the thickness of the capsule, and the relation of the abscess to the cerebral ventricular system. CT is very important in establishing the diagnosis of multiple, multichamber, and hematogenic-metastatic brain abscesses. CT provides for visualization of edema of the brain and changes in the ventricular system and subarachnoid fissures in patients with abscesses and for objective and exact evaluation of the radical character of removal of the abscess and the dynamics of reactive changes in the surrounding tissue.
